Rekordbox says Failed to Create Library with 40 Songs

 I've been using this program for a couple of years and have had many problems.  This one takes the cake.  I have 40 song all formatted to MP3 and at 320 Kps bit rate and all I get is "Failed to write to usb device."  I've deleted, reformatted, and still the same issue.  I have looked at other post here but none of them helped.  Rekordbox is the current version and the usb drive is formatted to fat 32 so what's the problem?  Can I analyze the songs without putting them into the library because this is simple a headache.
